Tris(ethane-1,2-diamine-κN,N')cobalt(III) carbonate iodide tetra-hydrate.

ABSTRACT: The title compound, [Co(C(2)H(8)N(2))(3)](CO(3))I·4H(2)O, crystallizes with a [Co(en)(3)](3+) cation (en is ethane-1,2-diamine), CO(3) (2-) and I(-) anions and four water mol-ecules in the asymmetric unit. In the cation, the three rings formed by the ethyl-enediamine units and the Co(III) metal ion are in slightly distorted twist conformations. Numerous O-H⋯O, N-H⋯O, N-H⋯I and O-H⋯I inter-molecular hydrogen bonds between the cation and two anions in concert with the four water mol-ecules dominate the crystal packing and create a supra-molecular infinite three-dimensional framework.

(μ-Ethane-1,2-diamine-κN:N')bis-[bis-(ethane-1,2-diamine-κN,N')zinc(II)] tetra-kis-(perchlorate).

Project description:In the title salt, [Zn(2)(C(2)H(8)N(2))(5)](ClO(4))(4), an ethyl-enediamine mol-ecule bridges two bis-(ethyl-enediamine)-zinc units; the five-coordinate Zn atoms show a trigonal-bipyramidal coordination geometry that is distorted towards square-pyramidal (that of one Zn atom is distorted by 12% and that of the other by 34%). The perchlorate ions are all disordered over two positions in a 1:1 ratio. The cation inter-acts weakly with the anion by N-H⋯O hydrogen bonds, generating a three-dimensional network.

Project description:The title compound, [Ni(C(2)H(8)N(2))(3)]I(2), crystallizes with an [Ni(en)(3) (2+)] cation (en is ethane-1,2-diamine) and two iodide ions in the asymmetric unit.

Tris(ethane-1,2-diamine-κN,N')cobalt(II) cis-aqua-2κO-μ-cyanido-1:2κC:N-hepta-cyanido-1κC-bis-(ethane-1,2-diamine-2κN,N')cobalt(II)molybdenum(IV) dihydrate.

Project description:The title compound, [Co(C(2)H(8)N(2))(3)][CoMo(CN)(8)(C(2)H(8)N(2))(2)(H(2)O)]·2H(2)O, is isostructural with the Ni(II) analogue. The Mo(IV) atom is coordinated by eight cyanide ligands, one of which forms a bridge to a Co(II) atom that is itself coordinated by two bidentate ethane-1,2-diamine (en) ligands and one water mol-ecule. Another Co(II) complex, coordinated to three bidentate en ligands, acts as the counter-ion. The crystal structure contains O-H⋯N/O, N-H⋯N/O and C-H⋯N/O hydrogen bonds, which form a three-dimensional network.

Tris(2,2'-bipyridine-κN:N')cobalt(III) trichloride tetra-hydrate.

Project description:The title compound, [Co(C(10)H(8)N(2))(3)]Cl(3)·4H(2)O, contains discrete [Co(bpy)(3)](3+) cations (bpy is 2,2'-bipyridine), Cl(-) anions and water mol-ecules. The [Co(bpy)(3)](3+) complex cation exhibits C(2) symmetry with the twofold axis through the central Co atom and bis-ecting one bpy ligand and one of the Cl(-) anions. The four solvent water mol-ecules and the remaining two Cl(-) anions lie on a mirror plane. Hydrogen-bond inter-actions define a two-dimensional layer structure parallel to (100), which consists of seven-membered [Cl(2)(H(2)O)(5)], eight-membered [Cl(4)(H(2)O)(4)] and ten-membered [Cl(2)(H(2)O)(8)] rings.

Project description:In the title complex, [Cu(H(2)NCH(2)CH(2)NH(2))(3)](CF(3)COO)(2), the environment of the Cu atom is distorted octa-hedral, formed by six N atoms from three chelating ethane-1,2-diamine ligands.
